Definitions

  • the invention relates to a smart card module and a smart card with external contacts comprising such a module.
  • the configuration of the contact zones of the outer face usually complies with standard ISO 7816, which specifies the presence of eight contact zones distributed in two parallel series of four contact zones having well-defined functions; these contact zones are usually denoted by the references C 1 to C 8 :
  • Contact zones C 4 and C 8 have not always been used in the past, but are being used increasingly, in particular for USB communications, or for SPI communications.
  • pad C 4 can have a reset, write or read function, or a function of D+ terminal for a USB function
  • pad C 8 can have a function of D ⁇ terminal for a USB function
  • standard ISO 7816 fixes the mutual positioning of the various contact zones, as well as the minimum dimensions of these contact zones, namely 2 mm wide and 1.7 mm high (by convention, the pads are arranged in vertical series, near the short sides of the carrier film (which has an overall rectangular shape with rounded corners).
  • the smart cards comprise a body in which a cavity is made for receiving said module.
  • Standard ISO 7816 also specifies the configuration of such a module within said card body.
  • This card body can have several formats, which are also standardized. Thus, three important standardized formats are used, known by the following references (see in particular standard ETSI TS 102 221 and standard ISO 7816):
  • a configuration with two series of contact zones intended to be connected to an underlying circuit, with two contact zones arranged between these two series of contact zones and intended to be connected to an antenna arranged in the card body, is also known from document WO-2000/043951 (Bull et al.).
  • a smart card connector having two parallel series of contact pads and at least one additional contact pad placed between the two series and extending in the prolongation of a pad of one of the aforementioned series, in the direction of a median line positioned at equal distance from these series, without going beyond this median line, which permits good compatibility with conventional card readers, is known from document EP-1 816 593 (Axalto).
  • the invention relates to a smart card module permitting size reduction below the 3FF format, while observing as far as possible the constraints set by the standards such as standard ISO 7816, and promoting, in addition, good mechanical performance.
  • the invention proposes a smart card microcircuit module comprising a carrier film provided, on a first face, with eight contact pads suitable for being brought in contact with an external element and, on a second face, with an electronic component equipped with connecting terminals to which the contact pads are connected via the carrier film, these eight contact pads being arranged in two parallel series of three contact pads between which two other contact pads are positioned, these series of contact pads each being aligned parallel to one and the same direction of the carrier film in such a way that the contact pads of one of the series are respectively opposite, transversely to said direction, to the contact pads of the other one of the series, the other two contact pads being respectively positioned near the contact pads forming the ends of each of the series, the contact pads each having, parallel to said direction, a dimension of at least 1.7 mm and, transversely to this direction, a dimension of at least 2 mm, the contact pads of the two parallel series complying with the provisions of standard ISO 7816 as regards the pads denoted C 1 to C 3 and C 5 to C
  • carrier film here is also called, depending on the circumstances, insulating substrate, or sticker, or flexible plate, etc.
  • each pad is located at a distance from such an edge that is of the same order as the spacing between these pads; in other words, the eight contact pads have a configuration such that their outer edges form a rectangle located in the immediate vicinity of each of the edges of the carrier film; thus, the space requirement of the contact pads on the carrier film represents almost all (at least 80%, or even 90%) of the surface of the carrier film.
  • the invention teaches abandoning the conventional arrangement, imposed by standard ISO 7816, of series of four contact zones, while preserving many geometric provisions of this standard.
  • the standard associates the contact pads denoted C 4 and C 8 (according to this standard) with a “future” application, to the point that some people have believed it possible to regard these pads as being optional.
  • document EP-1 819 593 envisages it, very evasively, without giving the least justification of the principle of eliminating pads called optional while adding additional pads; it may be noted in this connection that, in the examples of the number of additional pads recommended, this document mentions 1 , 3 or 4 , but not 2 .
  • the fact that, according to the invention, the size of the contact pads is not reduced, has the advantage that the accuracy constraints in the operations of component assembly are not increased relative to the existing manufacturing processes, even in the case of a reduction in size of the module.
  • component assembly is by flip-chip assembly, the carrier film having, on said other face, electrically conductive tracks connected respectively to the eight contact pads via the carrier film and having connecting pads opposite the connecting terminals of the component to which they are fixed.
  • flip-chip assembly of the components within the modules is much less common than assembly with wire connection, called wire-bonding, as the latter has the great advantage of allowing a carrier film to be prepared with its contact pads independently of the geometry of the electronic component that is subsequently to be fixed on it, which allows very high throughputs, as a simple change in parameterization in the wire connections makes it possible to change the type of components.
  • flip-chip assembly requires specialization of the carrier film at an early stage of production of the module, since the tracks must take account of the geometry of the connecting terminals of the future electronic component.
  • the component is only fixed to the carrier film via the connecting terminals of this component and connecting pads located opposite on the rear face of the film; however, it is preferable to supplement this mechanical bonding provided by the electrical connection with an interposed material filling the space between this carrier film and the opposite face of the component (conventionally this material is called underfiller); in a manner known per se, depending on requirements, the latter can be electrically insulating, or electrically conducting (anisotropically, only parallel to the electrical connections). It will be understood that the presence of said interposed material helps to ensure good rigidity of the module during placement of the component.
  • the carrier film comprises, on its first face, a reinforcing zone facing, through this film, the whole component.
  • the contact pads arranged on the first face of the carrier film are formed within a metallic layer, the reinforcing zone having the same thickness and the same composition as the contact pads.
  • the contact pads are conventionally delimited by etching of a metallic layer on its entire thickness, formation of this reinforcing zone can be carried out in the same way, preferably at the same time.
  • this operation of delimiting the connecting pads can be accompanied by a step of forming additional material so as to increase the thickness of the reinforcing zone relative to that of the connecting pads.
  • the reinforcing zone is integral with one of said other contact pads, i.e. the reinforcing zone and this pad can extend one into another without discontinuity; as a variant, it can be integral with one of the contact pads of one of the series, for example a pad forming the earth (the mechanical/electrical connection between the reinforcing zone and said pad can be provided by a right-angled or rounded zone).
  • the reinforcing zone is electrically insulated with respect to each of the contact pads.
  • said electrical insulation is accompanied by the fact that this reinforcing zone is separated from the contact pads by narrow strips of the carrier film that are not covered (by the material constituting the connecting pads or the reinforcing zone), which amounts to stating that the reinforcing zone is then mechanically independent of the connecting pads, these narrow strips forming zones that bend easily, helping to minimize the bending forces to which the reinforcing zone, and therefore the component on the other side of the carrier film, may be subjected.
  • the reinforcing zone parallel to said direction of the carrier film, has a larger dimension (by several percent for example) than that of the contact pads located in the middle of the series of contact pads, which contributes, conversely, to imparting a certain rigidity to the module as a whole, while allowing the aforementioned advantages of mechanical performance.
  • said other two contact pads are dedicated to a USB communication function, which constitutes a function of increasing interest in practice.
  • the configuration of the contact pads in series of three-two-three pads is not in any way incompatible with the fact that connecting terminals of the component to which the eight contact pads are connected are distributed in two parallel series of four connecting terminals. This amounts to stating that implementation of the invention does not involve a change in the configurations of the existing components, despite the change in configuration of the eight contact pads. In fact the configuration of the contact pads according to the invention does not impose anything regarding the locations of the connecting terminals.
  • the invention also proposes a smart card comprising a module of the aforementioned type, comprising a card body in which a cavity is made, comprising a deep part suitable for receiving the electronic component, which is surrounded by a peripheral part of reduced depth to which the module is fixed on its periphery.
  • all eight contact pads are opposite this peripheral part (it follows that the deep portion of the cavity is just larger, parallel to the carrier film of the module, than the component).
  • This allows a good increase in rigidity of the smart card, even when the card body is just larger (parallel to the carrier film) than the module; moreover, this contributes to the mechanical performance of the card when forces are applied, in particular during its separation from a larger substrate, since this has the effect of localizing the effects of such forces between the contact pads and the component, in the form of bending of the carrier film; this is particularly noticeable when there is a reinforcing zone and when the latter is mechanically independent of the connecting pads.
  • the aforementioned features are particularly beneficial for making a smart card the body of which has dimensions that are smaller than those of the 3FF format, i.e. less than 15 mm ⁇ 12 mm (the module can then occupy more than 80% (or even 90%) of these dimensions).
  • the arrangement of the contact pads of a module or of a card is reflected, face to face, in the arrangement of the contactors of a reader configured for connecting to such a module or such a card.
  • the invention thus proposes, in addition, a reader configured for connecting to at least one of said two other contact pads of a module (or of a card) as defined above.

  • each of the cards 100 or 200 comprises a smart card microcircuit module comprising a carrier film of overall rectangular shape provided with:
  • these eight contact pads are arranged in two parallel series of three contact pads, between which two other contact pads are located; these series of contact pads are each aligned parallel to one and the same direction of the carrier film in such a way that the contact pads of one of the series are respectively opposite, transversely to said direction, to the contact pads of the other of the series; the other two contact pads are respectively positioned near the contact pads forming the ends of each of the series.
  • the contact pads each have, parallel to said direction, a dimension of at least 1.7 mm and, transversely to this direction, a dimension of at least 2 mm; the contact pads of the two parallel series comply with the provisions of standard ISO 7816 as regards the pads denoted C 1 to C 3 and C 5 to C 7 in this standard.
  • These eight contact pads jointly border each of the sides of the carrier film.
  • card 100 comprises a module denoted 101 comprising a carrier film 102 equipped with contact pads 103 arranged on a so-called external face of the module, i.e. on the face of the carrier film that is visible from the outside when the module is mounted and fixed inside the card; these contact pads are suitable for being brought in contact with an external element, in practice a card reader (not shown).
  • This module 101 is fixed to a card body denoted 104 , which it may be noted is just larger than the module.
  • the contact pads 103 carried on the outer face of the carrier film are eight in number, as in a module complying with standard ISO 7816, but in an arrangement that differs from this standard with regard to two of the pads (see below).
  • the carrier film On its opposite face (not visible from outside), the carrier film carries an electronic component (not visible in FIG. 1 ) equipped with connecting terminals to which the contact pads are connected through the carrier film (this will be described in connection with the example in FIG. 2 ).
  • the eight pads 103 are distributed in two parallel series of three contact pads and in an intermediate series of two pads.
  • the contact pads of said series are denoted C 1 , C 2 and C 3 , on the left, and C 5 , C 6 and C 7 , on the right; these series of contact pads are each aligned parallel to one and the same direction of the carrier film (vertical in FIG. 1 ), in such a way that the contact pads of one of the series are respectively opposite, transversely to said direction, to the contact pads of the other of the series; in other words, pad C 1 is opposite, transversely to the vertical direction, to pad C 5 , pad C 2 is opposite pad C 6 and pad C 3 is opposite pad C 7 .
  • the other two contact pads they are respectively positioned near the contact pads forming the ends of each of the series; they provide the same functions as could be provided by pads C 4 and C 8 of a usual combination of eight pads; they are denoted C′ 4 and C′ 8 so as to reflect this similarity, the prime symbol indicating that they are not, however, completely identical (on account of their locations) to said pads C 4 and C 8 .
  • pads C′ 4 and C′ 8 are dedicated to a USB communication function, which complies with the purpose of pads C 4 and C 8 as defined in the recent version of standard ISO 7816-12. This purpose is indicated by the marks D+ and D ⁇ shown on these pads.
  • the eight contact pads each have, parallel to said direction, a dimension of at least 1.7 mm and, transversely to this direction, a dimension of at least 2 mm; moreover, the contact pads of the two parallel series comply with the provisions of standard ISO 7816 as regards the pads denoted C 1 to C 3 and C 5 to C 7 in this standard. It follows from this that the eight pads comply with the provisions of standard ISO 7816 except as regards the location of pads C′ 4 and C′ 8 .
  • These eight contact pads jointly border each of the sides of the carrier film.
  • the space requirement of the eight pads is just less than the area of this carrier film, the set of eight contact pads being such that each of the sides of the sticker is bordered by edges of three contact pads.
  • contact pads C′ 4 and C′ 8 have in this case a spacing of the same order of magnitude (just of the order of double) as the spacing existing between the pads of the parallel series.
  • the rectangles shown within the contact pads represent the minimum dimensions stipulated by standard ISO 7816.
  • one of the pads can extend as far as a dimension corresponding overall to the space requirement (in the vertical direction of the sticker) of a group of two lateral contact pads; for example pad C′ 8 can be extended until it has a similar vertical space requirement to that of pairs C 2 -C 3 or C 6 -C 7 .
  • FIG. 2 shows another embodiment example of a smart card according to the invention, and therefore another embodiment example of a module according to the invention.
  • card 200 comprises a module denoted 201 comprising a carrier film 202 provided with contact pads 203 arranged on a so-called outer face of the module, and this module is fixed to a card body denoted 204 , which it may be noted is just larger than the module.
  • the contact pads 103 carried on the outer face of the carrier film are eight in number, distributed in two parallel series C 1 -C 2 -C 3 and C 5 -C 6 -C 7 , on either side of pads C′ 4 and C′ 8 , as in the example in FIG. 1 , complying with the same provisions of standard ISO 7816 as the pads in FIG. 1 .
  • pads C′ 4 and C′ 8 are advantageously dedicated to a USB communication function.
  • these eight contact pads jointly border each of the sides of the carrier film.
  • the space requirement of the eight pads is just less than the area of this carrier film, the set of eight contact pads being such that each of the sides of the sticker is bordered by edges of three contact pads.
  • the carrier film On its opposite face (not visible from outside), the carrier film carries an electronic component 205 equipped with connecting terminals to which the contact pads are connected through the carrier film.
  • FIG. 2 shows a zone Z located between the contact pads C′ 4 and C′ 8 .
  • FIG. 2 shows, by transparency through the carrier film, component 205 , as well as its connecting terminals 206 ; it also shows connecting tracks 207 having end zones (here broadened and rounded), which are denoted 208 .
  • the electronic component is in fact mounted by flip-chip assembly, i.e. its connecting terminals 206 are located on the face of the component facing the carrier film; these terminals are each connected by a track 207 to an end zone 208 located under a contact pad.
  • these end zones are connected (see FIG. 3 ) by vias 209 to the contact pad positioned opposite on the front of the carrier film.
  • these vias are holes passing through the carrier film, the wall of which is metallized to provide an electrical connection between these end zones and these contact pads; these holes are blind in the sense that they pass through the carrier film, but not the contact pads.
  • the contact pads are arranged in three series of three-two-three contact pads
  • the component can have the conventional configuration of two series of four connecting terminals along two opposite sides of this component (in fact the configuration of the terminals on the component is not critical).
  • wire-bonding assembly between the connecting terminals of the component and the contact pads is an alternative for assembly of the component.
  • zone Z has a location and a surface area such that it is opposite, through the carrier film, to the whole component.
  • This zone Z has, in the example presented here, a thickness (see FIG. 3 ) equal to that of the contact pads; in fact, a practical way of producing this zone Z and the contact pads consists of forming an electrically conductive layer on the face of the carrier film and of etching this layer so that the contact pads and zone Z are delimited there. It will be understood that it is also possible to provide a larger (or smaller) thickness for this zone Z.
  • this zone Z has a role as reinforcement with respect to the component.
  • the terminals of the component that are connected to the ends of the tracks are formed by feet, called bumps 210 .
  • these bumps can have a tapered shape (with decreasing cross section starting from the component), so as to be able to penetrate into the corresponding pad 209 during application of the compressive forces for purposes of assembly.
  • This penetration can be enough to provide electrical connection between the component and the tracks 207 situated on the back of the carrier film, as well as a good mechanical bond between said component and said carrier film.
  • a filling material 212 (conventionally called underfiller) which enhances the mechanical durability.
  • an underfiller can comprise electrically conducting particles.
  • FIG. 4 shows a module fixed to the carrier film just by the aforementioned bumps, therefore without underfiller.
  • the elements in FIG. 4 that are analogous to those in FIG. 3 are denoted in FIG. 4 by references derived from those in FIG. 3 by adding a prime symbol.
  • electrical connection can be provided by electrolytic bumps, i.e. formed by electrolysis, which have the particular feature that their cross section is roughly constant; in such a case, the presence of an underfiller is in practice necessary to ensure the desired mechanical durability.
  • the card body 204 comprises a cavity receiving the module in such a way that the contact pads are flush with the upper face of this body.
  • a cavity is formed conventionally with a deep part and a peripheral part, surrounding this deep part, having a smaller depth; in practice the central part has a sufficient depth for accommodating the component, whereas the peripheral part has a depth just sufficient to receive the periphery of the carrier film, being attached to it by an adhesive (or any other fixing element).
  • this peripheral part denoted 204 A extends with respect to the set of eight contact pads, but not with respect to zone Z (in other words, the deep part of the cavity is just larger than the component).
  • FIG. 5 makes it possible to visualize the benefit of the presence of the reinforcing zone Z.
  • zone Z has the advantage on the one hand of distributing this force over a significant portion of the carrier film, which minimizes the risks of degradation of the latter.
  • this zone Z has the advantage of minimizing the bending forces imposed on the component and on its electrical connections with the carrier film, which constitutes an appreciable protective role.
  • the contact pads are opposite the peripheral part of the cavity, it will be understood that, since the periphery of the carrier film is fixed to this peripheral part of the cavity, it therefore follows that the contact pads are fixed more or less rigidly to this peripheral part, which also minimizes the bending forces imposed on these contact pads.
  • the main pressing forces to which the module may be subjected are translated into bending forces at the level of the narrow uncoated strips separating the various contact pads with respect to the reinforcing zone Z; since these zones are not covered, they constitute the most flexible parts of the carrier film, able to withstand these bending forces without degradation.
  • this reinforcing zone Z has, parallel to the direction of the series of three pads (perpendicular to the plane of FIG. 3 ), a dimension that is advantageously slightly greater than the analogous dimension of contact pads C 2 and C 6 between which this zone Z is located. This contributes to establishing a good compromise between the need for rigidity of the module and flexibility during pressing.
  • This pressing force is in particular applied at the time of separating the card body from a larger substrate within which the card was formed.
  • the pressing forces may be applied by the pad of a finger, but also by a tool, which justifies the concern to ensure good mechanical durability.
  • zone Z can, as a variant, be integral with one of the pads, i.e. zone Z can consist of one of the contact pads, preferably one of pads C′ 4 or C′ 8 , which would extend without discontinuity to the median part of the visible face of the carrier film (in other words, there would not be any demarcation between a portion forming a contact pad and a portion forming reinforcement). The role of mechanical reinforcement and protection of the component with respect to the bending forces would then also be obtained, despite less flexibility between the portion serving as contact pad and that serving as reinforcement.
  • zone Z can be connected to one of the contact pads of one of the series, for example to the earth pad C 5 (to do this it is sufficient to reduce the horizontal dimension, in FIG. 2 , of pad C′ 4 ). An intermediate option would be to provide a constriction of the layer forming this zone, between its reinforcing portion and its portion forming the contact pad.
  • the carrier film is made of PET, or even of FR4 or of PI, and its thickness can be about 50 microns (or even more, for example between 50 and 100 microns), and the contact pads as well as the connecting tracks are of copper, with a thickness of a few microns.
  • a person skilled in the art will be able to adapt the configuration of the contact zones of a card reader to enable connection to a module, or to a card, according to the invention, by locating, in particular, at least one contact zone opposite one of said other contact zones C′ 4 or C′ 8 of the module or card (depending on requirements, it is possible not to use one or other of zones C′ 4 or C′ 8 , or on the contrary use both of them); thus, the reader is configured for connecting to at least one of said other contact pads; preferably there are two contact zones opposite each of said other contact zones, respectively.
  • such a reader comprises a plurality of contact zones suitable for connecting to a plurality of the contact zones of the module, the relative arrangements of the contact zones of the reader following from those of the contact zones of the module, according to a mirror effect.
